I am looking for labelPro 3.0 for Windows

This is an older software item that is not as widely distributed as it
once was. Many online shops that used to carry LabelPro no longer do
so. I have found two online merchants that are currently offering
Avery LabelPro 3.0 for Windows:

Shop for Software: Labelpro 3.0 for Windows ($28.99)
http://www.shopforsoftware.com/catalog/product/196886/info.aspx

Pitney Bowes: Avery® LabelPro® 3.0 for Windows - Mfg Part # 5119 ($49.95)
http://www.pb.com/cgi-bin/pb.dll/jsp/ProductDetailShow.do?prod_id=916-2&categoryOID=-13689&store_id=pbs&lang=en&country=

I placed the product in my shopping cart to verify that each of the
merchants linked above has this item in stock (I removed the items
after having verified this, since I did not want to continue through
the purchasing process).

Here is an offer on eBay for only $4.98 plus shipping:

eBay: Sealed Avery Label LabelPro Software for Windows NR

You can download a shareware version of LabelPro 3.0 here:

Jumbo Big-Time Downloads: LabelPro 3.0

I downloaded the shareware LabelPro from the link above to verify that
the link functions. The download was rapid, and the software installed
properly.

Google search strategy:

Froogle: "labelpro 3.0" + "windows"
http://froogle.google.com/froogle?q=%22labelpro+3.0%22+windows

Google Web Search: "labelpro 3.0" + "windows"
://www.google.com/search?hl=en&ie=UTF-8&q=%22labelpro+3.0%22+windows

I hope this helps you to obtain the software that you need. If
anything is unclear, or if a link doesn't work for you, please request
clarification; I'll be glad to offer further assistance before you
rate my answer.
